To all whom t may concern.'

Be it knownthat I, JAMES A., BISHOP, a citizen of the United States,residing at Masccutah, in the county of St. Clair and Sta-te ofIllinois, have invented certain new and useful Improvements inContinuous-Process vCoke-Ovens, of which the following is aspecification.

The present invention has reference to certain improvements in cokeovens of that general type in which the coking operation is continuousas distinguished from the type in'which separate charges of coal areindividually coked. The invention has to do, among other things, withthe general form of the oven, the manner in which the same is heated,the manner in which the coal is introduced into one portion of thecarbonizing chamber, and the manner in which it is removed from anotherportion thereof.

One of the objects'of'the present invention `is to provide a` continuousprocess oven of such form and construction'that the coal can be veryrapidly coked, so as to reduce the coking period to a comparativelyshort time.: This will increasethe tonnage capacity of aplant of givensize as compared to itsy capacity when operating at a lesser cokingrate.

Another object is to provide means for securing a kuniform distributionof the coking material throughout the carbonizing chamber, insuring, atthe same time, a uniform and regular travel of the material from thepoint ofinlet for the raw material to the point of delivery for thecoked product.

Another object of the invention is to pro vide means for continuouslyand perfectly cooling the distributing device, so that the same willnot` be injured or` rendered in: operative, by reason of the hightemperature existing within the carbonizing chamber.

Other objects and uses of the invention will appear from a detaileddescription of the same which consists in the features of constructionand combinations of parts hereinafter described and claimed.

yIn the drawings, Figurev l is a vertical section through aconstructionof oven embodying the features of the present invention, thedischarge port being partially open; it being a section taken on line 11 of Fig.

2, looking in the direction of the arrows;

FigLQ is a horizontal section taken on line i :2 2 of Fig l, looking inthe direction of the arrows; and Fig-3 is a horizontal section taken online 3 8 of Fig. l, looking in the direction of the arrows.

Referring to the several figures, the particular construction of ovenillustrated may be considered as being made up from three divisionsbroadly numbered l, 5, and 6, respectively. rIhe division 4 is in the,nature of a foundation for-the structure, and at the same time itaccommodates certain of the operating mechanisms. lllhe division 5 maybe termed the heating di-vision, and it is in this division that theheat is generatedvfor heat- -ing the carbonizing chamber. The division 6is the carbonizing division, comprising the carbonizing' Achamber andthe distributing device or mechanism contained therein.

I have thus described the apparatus as sub-divided into three divisionsmerely for purposes of convenience, and it 'will be understood that thefmechanisms shown in changed between the different divisions, or`

certain of the divisions may even be eliminated entirely. Thecarbonizing chamber has-the ioor 7 and the dome-shaped roof 8. As showninFigs. 2 and 3, the carbonizing chamber is preferably circular in form,in-

asmuch as a simple type of distributing'de- .vice is one which rotatesabout a` yvertical axis. rIhe heating division is shown 'more in detailin F ig. 2. It is provided around its periphery with a number offurnaces or grates 9, wherein are generated the heating gases by means-of which the .carbonizing chamber is heated effectively for thedistillation of the coal. Leading from the furnaces 9 are heatingpassages which surround the floor, sides, and roof of the carbonizingchamber, so as to heat the same as uniformly as possible. Invtheparticular arrangement illustrated, there are provided in the heatingdivision a plurality of radial passages 10 and a plurality of radialpassages l1, there being as many of each of the passages l0 and l1 asthere are furnaces 9. The heating gases from each furnace 9-travelinwardly along the corresponding passage l0, and lthen turn and tra-veloutwardly along the corresponding passage 1l, the passages 10 and l1being connected together in pairs ends, as best shown in Fig.,2.'

' In the roof o f the structure, there are a plurality of radialpassages 12, or a single at their inner :the yseveral divisions maybelargely interf large space 12, depending upon the form of constructionadopted, having its outer portion adjacent to the periphery of thecarbonizing chamber and having its inner portion communicating with aspent gas iiue 13. The outer ends of the passages 12 communicate bymeans of vertical passages 14 in the peripheral wall of the carbonizingchamber with the outer ends of the passages 11. From the foregoing, itwill appear that the heating gases, after having traveled toward andfrom the center of the structure in theheating device, thereafter travelup and' over the carbonizing chamber to the spent gas delivery flue 13.Thus, the arrangement is such that the carbonizing chamber 'is heated onits bottom, its side walls, and

its roof.

The coal is introduced atthe central portion of the carbonizing chamber,and is v,caused to travel toward the periphery thereof, being dischargedat a suitable point on the periphery after having remained in the ishown in Figs. 1 and 3.

carb'onizing chamber the desired interval of time. thedistributingYdevice 14a which is best The same comprises a vertical axial memberwhich carries a plurality of radial arms, the radial arms being providedwith scrapers or shovels whose function is to cause the carbonizing massto travel toward the periphery and toward the discharge point.

The coal is delivered into the carboni-Zing chamber through a centralopening or pocket 15. Leading up to this pocket is a tubular passage 16`within which is shown the screw conveyer' 17. The conveyer transfers thecoal from a hopper 13 to the pocket 15. The distributing devicecomprises the vertical axial member 19 which carries a plurality ofradial distributing arms 20. Each of these arms is provided with shovels21 set at different-radial positions onthe arms, ,so that, as 'thedistributing device rotates, the scrapers will transfer the coalsuccessively farther and farther from the center, and thus eventuallydeliver it to the point of delivery. To insure this result, the shovelsare so placed as to form a` spiral,

- as shown in Fig. 3, instead of being placed yon tangents to circlesdrawn about the cen- For this purpose, I have provided of cooling wa'terto the chamber. From the chamber, this cooling water [lows radiallyoutward through the pipes to the members 26. The upper axial portion 2Tof the distributing device is also hollow, but does not coi'i'imunicatedirectly with the chamber 25. 0n the other hand, correspoinling to eachof the arms 20 there is a pipe 28 leading from the member 2U up and intocommunication with the member 2T, so that the cooling water will be-delivered through the pipes 2S to said member.

Extending upward from the foundation of the structure and through theheating division is a bearing member 29. This bearing member has aflange 30 which -is supported by the foundation and serves to transmitthrust from the member 2S) to the foundation. The hollow cliamberedineinber 25 rests on the upper end of the member 29, which thus providesa bearing on which the distributing device may rotate. A stuliing box 31between the member 2S) and the hollow axial member 19 serves to preventa downward flow of gas from the carbonizing chamber. Anysuitable meansmay be provided for rotating the member 19 and therewiththe distributingdevice. For this purpose, I have illustrated a worm gear 32 driven bythe worm 33. A pipe 34 delivers the cooling water to the 4axial member19, a stuing box 35 providing a water tight connection between theseparts.

Leading upufardly from the roof of the carbonizing chamber is thedistillate gas delivery pipe 36. This delivers the distillate. gases to'the pipe 37, from which they may be carried to ahy-product recoveryapparatus, or ,to any other point of disposition desired. The upperhollow axial member 27.13rojects above the pipe 3G and communicates withthe cooling water delivery pipe 38. The stuffing boxes 39 and 4()prevent a leakage of cooling water at the point of connection into thepipe 38 and prevent a n leakage of gas at the point of exit from thepipe 36, respectively.

At any suitable portion in the periphery of the carbonizing chamber.there is a coke delivery .opening 41, best shown in Fig. 1.

, A downwardly extending chute 42 conveys the coke from this openinginto a receiving chamber 43 from whencethe coke may be removed throughthe door 44. By luting in the door 44 soas to close the chamber 43, cokemay be collected from an interval of run, and cooled preparatory toremoval into the atmosphere, A horizontally traveling door 45 isprovided for closing the chute 42. This door has the threadedsleeve 46work- `ing in a bearing 47 within which it may travel horizontally andwithout rotation. A crank 48' on the 'threaded rod 49 working withrespect to a stationary member 50, serves to force the threaded sleeve46 back idear/5 a sight hole or opening, through which the operation'ofthe coking process may be 0bserved. The construction illustratedincludes a vtile 53 extending through the side wall ofthe carbonizingchamber and carrying at itsouter end a cap member54. `This cap memberhasthe outwardly extending neck 55 which closed by means of a w'indow ofmica 56. `By looking in through the mica window, the operation of thecarbonizing process may be observed, and also the operation of thedistributing device. A partition 57 is clamped between the tile and thecap member. rIhis partition has a door seat 58 extending at an angle oflapproximately degrees to the axis of observation. The observer ylookingthrough the window' 56 also loo-ks through the seated opening 58 to theinterior of the carbonizing chamber.l

A door 59 may be carried into engagement with the seat so as to closetheopening thereof by means of the threaded pin 60 `profided with thehand wheel Gl. Y By means of this construction, the door may be closedat all times except when' it 'is desired to make an observation, thuspreventingl the blackening of the mica window. While I have shown thepin G0 as lying in the same horizontal plane with the aXis ofobservation, still it will'be understood that this pin might lie in anyother plane desired, and that, as far as this feature of construction isconcerned, the main point is that the door 59 travels along an axislying at an angle tothe axis of observation. y.

-`While I have herein shown and described only a single-embodiment of myinvention,

still it will be understood that I do not limit f y myself vto the same,except as I may-dose in f the claims, but that I contemplate within thesco-pe of my invention any equivalent constructions operating inequivalent manners to produce equivalent results.
